presentiiivention relates to an elec} tric advertising device or thellke, whereby a spotlight isTenabled to throw-its light in oppositedirections. Qne object of the present invention isto provide anilluminable sign m emberjor vthe-like'at the front of the device and areflector facing rearwardly at the back, of the device, between whichsign member and" reflector an electric lamp is arranged, theConstruction and operatloni of the device being such that one and thesame lamp may be used to illuminate the sign member and to act as a spotlight whose rays are cast rearwardly by the reflector upon goods whichmaybe on display in a show window for example.

Further objects of the present invention are, to provide means for somounting the lamp and reflector that the rays of light may be cast inmany directions rearwardly, this being desirably accomplished by'somounting the lamp and the reflector that'they may be inclined withreference'to their fixed axial position, the reflector and lamp-beingalso mounted so 'that they may be rotated about the main axis of thedevice. These being among the objects of the present invention the sameconsists of certain features of construction and combinations, of partsto "be hereinafter described and then claimed, with reference to theaccompanying drawings illustrating a preferred embodi me-nt of'theinvention and 'in which Fig.1"is a diametrical secti'onal elevation ofan electric-advertising device constructed according 'to' thepresent-invention; f j Fig; 2 is a sectional elevation thereof onthe-line22Fig-1;and" g Fig. 3 is a sectional elevation of Fig. 1 on theline 3-8, but on a sm'aller'scale.

Referring to the drawings, a'circular enclosing frame'lO of sheet metalis provided, theinner' surface of the frame .being preferably formed asa reflecting surface. Frame 10 is provided with an outward annular'rim11 upon which is adapted to be movably or permanently fitted an annularauxiliary frame 12 formed of angle metal and providing a front openingfor the device; Between the rim 11 and the au'xiliary'frame' 12 therethe front opening,

net a tight one, thefit should befairlys'nu'g four' guide members 20, 20ofwhich' two of is-fitted a glass plate lgwhichmay have any Y desiredadvertisement written or placed} upon it, so that it'constitutes a'signholder or sign member, the sign being illuminable'by means of lightrays projectedforwardly. "The frame 10 is provided with a rear opening1e which is quite small, relatively to the size of 'and,iat theopeningfor the back, the frame lO is provided with an outwardly andinwardly spun flange 15 Between the sign holder 18 and the -back of theframe, considerable space is desirably provided. Q i

Bulging rearwardly from frame lO there is a "substantially hemisphericalshield "16 of sheet metal, the larger diameterof whichisapprcximately'equalto the diameter of the opening 14: in frame 10.Shield 16' isprovided with a front opening 17 and at its rear, witha'relatively smaller opening or aperture18; i Preferably-the aperture 18extends from the central portion of the shield to a point adjacent'totheedge, that is me, radial direction as clearly shown in Fig. 3; Shield 16isalso provided with-an outward annular flange 19 atfront which flangeis. received in agroove-formed by the outwardly and in.-: wardlyextending flange 15 of the frame 10.

but loose enough soas to perinitthe turning or rotation of the shieldabout its major axis,

for reasons to be hereinafter'explained.

r The shield 16 is provided with preferably 5 them extend in onedirection 1 and: the other two in the opposite direction, that is tosay,

theseguide members extendradially along the inner surfa'ceof shield 16.One member of one pair 10f guide members extends along one'edge of theradial aperture 18 while the other member extendsjalongthe other edge ofsuch aperture". Each pair of guide memhers 20, 20 is preferably composedof angle metalwhichjmay be welded, brazed or soldered to the shield 16.One pair of the guide members 20, 20 is provided with forwardprolongations 21, which will be seen in Fig. 1 to extend intothe'spacewithin thecasing frame 10. Preferably each of the guidemembers" formed by the other pair of guide members.

When the parts of the lamp are adjusted to the position shown in fulllines in Fig. 1 the twoaprons 22, 23 will be so set that apron 22closes. theouter half of the radial aperture or1s10t-18 in the shield j.

A reflector 24 is providedwhich is preferablyof less dimensions than theshield 16,

the reflector being made of sheet metal and of substantiallyhemispherical shape. ,By means of a neck 25 on the reflector it is sosetandassembledwith the other parts of the deyicej as to facerearwardly. At the rear edge of'the reflector is an annular frame 26 ofangle metal fitted thereover. Between the edge ofthe reflector 24 andthe annular frame 26 there is fitted a glass plate or. lens 27, which is:retaine'din place by means of one or more set screws 28. Theneck 25 ofthe reflector is set in the rear end of the radial aperture 18-of theshield and it is welded, brazed ,or soldered to both aprons 22, 23 atthe inner edges thereof, so that saidaprons may extend diametricallyopposite each other. In some such way the reflector 24C and the apronsare unitedtogether to form a unit. V

' An electric lamp 29 is set within the forward'opening formed bytheneck 25,'the bulb extending rearwardly, while the socket memberwor' neck30 of thebulb is located in the space withinthe main frame 10. Lamp 29is supported in a fixed position relatively to the reflector 24 by meansof tubular supports .3lwhich are rigidly fixed to lateral guidingportions which connect the two aprons 22, 23, there beingan opening 41formedbetween the two aprons and the flanges 40, through which openingthe electric lamp 29 extends.

:The forward ends of these supports 31 are rigidly attached 30 of thelamp. v 7

The conductors for the lamp are led to socket portion or neck throughone of the tubularsupports 31 in the form of a cable 32-which is passedthrough and. secured in the apron 22, so that the cable 32 may passthrough the aperture 18 to the source ofYcurre'nt. The electricadvertising device may be provided with feet 33 so that it may be restedupon a counter or in a show window and with hangers 34 whereby it may besuspended if desired behind a plate glass window.

.The. preferred general construction and arrangement of the assembledparts of the adjusted in the guide members 20 In the positionshown inFig. 1 it will be seen that the axis of the reflector and the lampextend along tlie',1najor-axis of the device, as shown in the fulllines. New by loosening the set screw 35 of the aprons, the reflectorand the lamp may be adjusted so that the axis of the lamp and reflectorwillstand at an inclination to the position shown inFig. 1 in fulllines.

That is tosay, the reflector and lamp may be adjusted to the positionshown. in broken lines inthe'upper part of Fig. 1 in which position theflexible apron 22 will have; been shifted forwardly and outwardly intothe prolongations 21 of the guide members. In such position the flexibleapron 23 will have been moved across the rear one half of the radialaperture 18 so as to cover it.

1 A set screw 36 passes through a bracket 37 fixed to the outer surfaceof theshield 16 and near the forward edge of the shield. By means of setscrew 36 the shield 16 andthe parts carried thereby may be loosened topermit their rotation, the terminal of the set screw 36 being adapted torigidlybear upon the back of the frame 10 whereby to set the saidparts'against rotation. Now with the reflector and lamp set in an inclinedposition shown in the upper part of Fig. 1 it is perfectly obvious thatby loosening the set screw 36 the reflector and lamp together with theshield 16 may be rotatedfor a half turn to bring the lamp and reflectorfrom the broken line position referred ,to to the broken line positionshown in the lower part of Fig. 1'.

By reason of'the two-fold adjustment of the reflector and lamp it willbe seen that rays of light from the lamp may be cast rearwardly inv anydesired direction into a showwindow so as to more prominently illuminatecertain, goods in such: window in contrast with other goods; It willalso be seen that while thelamp acts as a spot light for such displaypurposes it also illuminates'th'e sign"memher or the like 13 which is atthe frontofthe device The members are so constructed that no matter whatthe adjustment of the lamp with reference to the stationary parts may.be, itis adapted to cast its rays forwardly without obstruction whichmight be incidental to the many possible adjusted positions of the lamp.It will'be seen that the apron 22 being guided forwardly into thespace'of frame 10 and being'deflected outwardly by reason of-the outwardextension of the 'prolongations-21, the apron, when so adjusted, cannotinterfere with the rays of light cast forwardly by the lamp. If there beany interference at all it is so slight as to be unworthy ofconsideration.

Whatever may be the form of the sign or the like which is mounted at thefront of the display device it is preferable to removably mount the samein position and to this end the annular auxiliary frame 12 may beposition by a catch 39. r e I It will be obvious to thoseskilled in theart that the invention as described and illustrated is susceptible tomore or less modifica- 15 of the invention as defined in the appendedclaims.
